A date nail is a nail with a year stamped on its head. The year is given in terms of the last 2 digits, e.g. ’41’ represents 1941. Date nails were driven into railroad dies, bridge timbers, utility poles, mine props, and other wooden structures for record keeping purposes. Most were made of steel and measure 2 1/2" long, with 1/4" shanks. Tokens & Icons mills the shank diameter down to create a post-style cuff link. Available years range from 1930 to 1970, meaning there are some easy gift possibilities: buy a cufflink-wearing gentleman his birth year assuming he was born in those 40 years, or buy him his age assuming he’s between 30 and 70!
